PORTABLE OVEN.

Specification of Letters Patent.

Patented Aug'. 26, 1913.

Application filed .T une 19, 1912. Serial N o. 704,654.

To all 'whom t may concern.'

Be it known that we, ANDREW JUDsoN Ross and THOMAS E. FRY, citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Portable Ovens, of which the following is a specification.

This invention relates to portable ovens, and is an improvement over the oven shown in the application bearing the Serial No. 674,731. `The improvement in this invention over that shown in the previous application resides in the device which applicant has for collecting the heated gases from the burner and conducting them into the interior of the oven.

The principal object of the invention is to so construct the conveyer that the heated gases will be prevented from coming into immediate contact with the walls of the oven, and thereby be prevented from over heating or burning out the sides of the oven.

Another object of the invention is to so construct the distributing device that it will act as a support for bracing the oven, thereby preventing the oven from slipping off the top of the stove when placed upon the stove with its major portion overhanging the side of the stove.

In the accompanying drawings Figure 1 is a bottom plan view of the oven. Fig. 2 is a vertical sectional view through the oven. Fig. 3 is a vertical sectional view through the oven taken 0n line 3-3, of Fig. 2, and looking toward the front end of theJ oven. Fig. Ll; is a top plan view of the distributing device. Fig. 5 is a fragmentary view of the distributing device showing the manner of connecting the bracket with the device.

Referring to the accompanying drawings it will be seen that this invention comprises a body portion 10, the side walls of which comprise the spaced sheet metal plates between which there is embedded a layer of asbestos or some other material. The top of the oven is provided with an opening to permit of the proper circulation through the oven. A plate 11 is mounted in the body portion above the bottom 12 and a vertical plate 13 leads from the inner end of the plate 1l to a point adjacent the top of the body portion. This vertical plate 13 is provided with side flanges 14 by means of which it is secured to the side walls of the body portion and held in spaced relation to the rear wall. Tracks 15 are mounted upon the side walls and are positioned in alineinent with the openings 16 formed in the vertical plate 13, so that curved tongues 17 extending from the inner ends of the trays 18 may pass through the openings 16 into the space between the vertical plate 13 and the rear wall when desired. The air in the space between the plate 11 and the bottom 12 is heated and thus heats the lower portion of the oven. This heated air passes around the conveying member into the space between the plate 13 and the rear wall of the oven and with the heated air from the burner is guided out beneath one of the trays 18 by moving the tray inwardly so that the curved tongues 17 will be moved into the space between the plate 13 and the rear wall of the oven.

This oven is placed upon the top of the gas stove and the heated gas of the burner indicated by dotted lines in Fig. 2 passes up through a conveying device which gathers the heated gases and conveys them into the heated space between the plate 13 and the rear wall of the oven. This conveyer is formed from two sections which are secured to the bottom of the oven by means of bolts passing through the iianges 19 carried by the two sections of the conveyer, the sections being so constructed that they form the circular mouth piece 20, the sides of which are brought together to form a rectangular outlet 21. This mouth piece is provided with a vertical wall 22 which is carried up into the space between the plate 13 and the rear wall of the oven and rests against the rear wall as clearly shown in Fig. 2. A short flange 23 extends from the rear wall 22 and is positioned beneath the rear wall of the oven, so that the oven will be supported and vertical movement of the conveyer limited.

Brackets 24 are secured beneath the flange 23 and fit beneath the top of the stove as indicated in Fig. 2, so that the oven is prevented from tilting forward and dropping over the side of the stove. The forward wall of the mouth piece is sloping as shown in Fig. 2 so that the heated gases will be concentrated and conveyed into the oven. A plate 25 extends upwardly from the mouth piece and lits against the plate 13 with its reduced central portion 26v fitting between the two lower openings 16. After this conveyer has been connected with the oven, the oven is placed upon the side with the mouth piece positioned above the burner and the heated gases pass into the mouth piece and up between the plates extending into the oven. These plates together with the mouth piece protect that portion of the oven which comes in close Contact with the burner, thereby protecting the oven and preventing it from being burned out or otherwise injured by the heated gases. pass between the plate 13 and the rear wall of the oven and serve to heat the interior of the oyen, so that articles of food may be cooked therein. If it is desired to direct the heated gases beneath the tray the tray is pushed inwardly so that its tongues pass through the opening 16 into the housing thereby directing the gases beneath the desired tray. AIt will therefore, be seen that this conveyer performs the two functions of conveying the heated gases into the interior of the oven and protecting the oven against damage from the heat. This Adevice also acts as a means for connecting the oven with the These heated gases stove to prevent it from falling ofi of the stove when placed as shown in Fig. 2.

Having thus described the invention what is claimed, as new, is

An oven comprising a body portion, a vertical plate mounted in said body portion in spaced relation to the rear wall thereof, a mouthpiece entering through the bottom of said body portion and extending into the space between said vertical plate and the rear wall of said body portion, a ange carried by said mouth piece for connecting the same with the bottom of said oven and eX- tending beneath the rear wall thereof, Aand brackets carried by said mouth piece and positioned beneath the rear wall of said oven.

In testimony whereof we affix our signatures in presence of two witnesses.
